Abstract

The invention provides a fault diagnosis method of a multi-water-pump water supply system, and belongs to the technical field of water supply systems. According to the fault diagnosis method of the multi-water-pump water supply system, each of monitoring sensors separately collects and outputs water pump operation information associated with water pumps; a fault diagnosis module receives the waterpump operation information and analyzes and processes the water pump operation information according to a preset fault analysis program to acquire and output fault information associated with the water pumps; and an Internet of Things communication module receives the water pump operation information and the fault information, and sends the water pump operation information and the fault information to a control end. The fault diagnosis method of the multi-water-pump water supply system has the beneficial effects that the multi-water-pump water supply system integrates the Internet of Things communication module to realize the communication function, the state and fault information of a water supply device can be continuously sent to the control end, the running state and the fault of thewater pump can be grasped in time, reaction to the fault is made in time, downtime is shortened, and the maintenance interval is shortened.

Description

technical field [0001] The invention relates to the technical field of water supply systems, in particular to a fault diagnosis method for a multi-pump water supply system. Background technique [0002] The current mode adopted for constant pressure water supply is to use general or special frequency converter to drive asynchronous motor to realize constant pressure water supply. Generally divided into two modes, one is the programmable logic controller (Programmable Logic Controller, PLC) + frequency converter + AC asynchronous motor + water pump; the other is to use the simple control function of the frequency converter, frequency converter + AC asynchronous Motor + water pump, the difference between the two is whether there is a PLC controller. The problems with this water supply method are: [0003] The system does not have the communication function of the Internet of Things, and it is difficult to find the operating status and fault information of the system in time,...
